PD 153035 Hcl (ZM 252868; AG 1517) is a potent and specific inhibitor of EGFR with Ki and IC50 of 5.2 pM and 29 pM; little effect against PGDFR, FGFR, CSF-1, InsR and Src.

Overactivity of the epidermal growth factor receptor-associated tyrosine kinase (EGFR) has been associated with cancer development and progression, including cell proliferation, apoptosis, angiogenesis, and metastatic spread.PD 153035 is a highly potent, reversible inhibitor of the EGFR (Ki = 5.2 pM; IC50 = 29 pM).It has been shown to rapidly suppress autophosphorylation of EGFR in fibroblasts and human epidermoid carcinoma cells, as well as to selectively block EGF-mediated cellular processes, including mitogenesis and early gene expression.
